[Class 108 (i).] A vehicle body for refuse collection has an end or side formed by a partition capable of being moved relatively to the remaining end and sides or ends and side so as to vary the effective capacity of the body, the partition acting in conjunction with a cover. In one form, a frame is mounted on rollers 8 which run in the lower trough-shaped portions 7a of channel bars 7. The partition 10 is hingedly connected to the rear of the frame and is provided intermediate of its top and bottom edges with bolts 11 adapted to be engaged, when required, within holes formed in the body sides. Hinged filling-doors 12 are operated, on depressing the treadle 15, by the roller ends of levers 13 engaging the doors 12. A flexible cover 16 reinforced by parallel slats 16a whose ends register in the inturned channel bars 7 is connected to the front edge of the frame. When the partition is in the position shown in Fig. 1 the cover is contained in the ends 7b of the channel bars 7. When the body has been filled up to the partition the bolts 11 are withdrawn and frame 9, with the partition 10, is drawn back causing the cover 16 to cover the refuse already deposited in the body. Means are provided for tilting the body. In a modification, Fig. 4, the cover is mounted on a roller 18 carried by the endplates 9a. A sprocket wheel 21 and a chain 20 may be arranged to rotate the said roller and one of the frame rollers 8 may also be rotated from the sprocket wheel. In a further modification the rollers 8 and channel troughs 7a may be replaced by flanged rollers running an opposite edges of the body. The steps 17 may be dispensed with, in which case the rear end of the floor of the body is inclined downwardly. The Provisional Specification also describes mounting of the cover on a spring roller.

Filed: 1973-02-08
Abstract: 1426642 Circuit breakers SIEMENS AG 8 Feb 1973 [19 April 1972] 6343/73 Heading H1N In a circuit breaker which opens when tripped a spring 65 resetting the latching lever 56 of the tripping mechanism is coupled to the switching operating shaft 40, on whose angular position depends the opening and closing of the switch, so as to be stressed when the switching shaft rotates on tripping of the circuit breaker. In closing the switch from an open position, toggle levers 42, 43, are brought into line against stop 46 thus rotating freewheel lever 47 so that roller 52 is displaced carrying with it lever 51 and thus switch lever 54 to turn switch operating shaft 40. Roller 55 associated with roller 52 runs along the inner edge of latching lever 56 which is held in position by a lug 62 bearing on a shaft 63. When the circuit is automatically broken this lug 62 is released by the rotation of shaft 63 and the latching lever falls free about pivot 60 so that roller 55 in contact with its inner edge is freed allowing associated roller 52 to move away from its position holding freewheel lever 47 which can then turn rotating the switch operating shaft 40 to the open circuit position. Deflection of the switching lever 54 on breaking the circuit causes the associated spring 65 to flex about a stop 70 on the latching lever and become stressed so as to be capable of returning the latching lever to its latched position ready for circuit closing. Further this deflection of the switching lever causes a traction spring 72 to be tensioned which urges the toggle levers back into their open circuit position.
